Effect of Cu2O Substrate on Photoinduced Hydrophilicity of TiO2 and ZnO Nanocoatings

Maevskaya, Maria V.; Rudakova, Aida V.; Emeline, Alexei V.; Bahnemann, Detlef W. (Basel : MDPI, 2021)

The effect of a Cu2 O substrate on the photoinduced alteration of the hydrophilicity of TiO2 and ZnO surfaces was studied. It was demonstrated that the formation of heterostructures Cu2 O/TiO2 and Cu2 O/ZnO strongly changed ...
Effect of the Type of Heterostructures on Photostimulated Alteration of the Surface Hydrophilicity: TiO2/BiVO4 vs. ZnO/BiVO4 Planar Heterostructured Coatings

Maevskaya, Maria V.; Rudakova, Aida V.; Koroleva, Alexandra V.; Sakhatskii, Aleksandr S.; Emeline, Alexei V.; Bahnemann, Detlef W. (Basel : MDPI, 2021)

Here, we report the results of comparative studies of the photostimulated hydrophilic behavior of heterostructured TiO2 /BiVO4 and ZnO/BiVO4, and monocomponent TiO2 and ZnO nanocoating surfaces. The chemical composition ...
Wear investigation of selective α-Fe2O3 oxide layers generated on surfaces for dry sheet metal forming

Behrens, Bernd-Arno; Yilkiran, Deniz; Schöler, Simon; Özkaya, Fahrettin; Hübner, Sven; Möhwald, Kai (Amsterdam : Elsevier B.V., 2018)

To realize a dry sheet metal forming process, α-Fe 2 O 3 oxide layers were investigated regarding their friction characteristics, wear behavior and surface energy depending on different surface qualities of the specimens ...
